Care must be exercised before upgrading or changing
hardware for any member of a GiCAP group. If a member of a GiCAP group
changes hardware in such a way that the hardware is no longer compatible
with the group, then the group is considered to be out of compliance
and group functions are restricted.
Also, note that the number of available Sharing
Rights is adjusted whenever an iCAP codeword is applied to a GiCAP
member system which modifies the number of cores without usage rights
on that member. (RTU and AddOn codewords for cores cause such adjustments.)
If available Sharing Rights go negative (more
in use than were purchased for the Group Manager), then all groups
managed by that Group Manager are out of compliance and all group
functions are restricted until the problem is resolved. The problem
can be resolved by purchasing and applying additional Sharing Rights
to the Group Manager, purchasing and applying core usage rights (RTUs)
to one or more group members, or by removing one or more group members
from their group.
When such an incompatibility is detected, the
GiCAP Group Manager sends e-mail to the local root account and to
the registered contact e-mail address for each member of the group.
Adding New Partitions |
 |
When reconfiguring a member system by adding or
deleting an nPartition, you may use the icapmanage -u command to add or remove host names to or from the member. For example,
to add a new nPartition with hostname hostC to
member memberA:
icapmanage -u -m memberA -h hostC |
To remove a host name, prefix the host name with “!”, as in “!hostC”. You may also add or remove a list of hosts; separate the
additions from the removals with a “!”, as in “hostA,hostB!hostC,hostD” to add hostA and hostB while
removing hostC and hostD.
If the Group Manager is run on a partitionable
system, changing the configuration of the partitions may result in
the Group Manager becoming inoperative. This is because the Group
Manager database is tied to the serial number of the complex, the
nPartition id number and a virtual partition id number. Although adding
or modifying partitions will not change these ids, they will be changed
if a partition is deleted and recreated on the Group Manager.
